Hello Alan,
You are quite right, I don't understand the complexities of of line
layout in HTML, but appreciate it must be very complex.
Thank you for the examples, I have used em's in the pastand appreciate
their valuebut found they get difficult when elements have been nested
several levels deep but the rem should fix that once we have better
browser support. I will experiment further myself.
I still think that my query is something that should be considered as
it'll aid creating layout, I see it working exactly as it does now, but
optionally all the space is applied below each line.
Also, as you noted headers in multi-column do need looking at -

Thanks for considering my suggestions, it's what makes the Internet what
it is.
Kind regards
Ric
